SHEET 3 UF 3 INVENTOR FRITZ STAH'LECKER BY Graig, flnl'onell, Stewart H-i ATTORNEYS SPINNING DEVICE FOR SPINNING THREADS BY THE OPEN-END METHOD The invention relates to a spinning device for spinning threads by the open-end method with a spinning turbine and with guiding elements for the fiber material which are movable in relation to the spinning turbine and render its open side accessible from outside.

It is known to remove the guiding elements, which are located on the open side of the spinning turbine and project partly into it, to such a distance from the spinning turbine that the interior of the spinning turbine becomes accessible, for example for the purpose of eliminating blockages due to thread breakages. To this end the guiding elements are accommodated in a swivelling housing which is kept in the operating position by a pawl locking device. To open the spinning turbine the pawl is manually released and the housing, together with the guiding elements, is swung away by hand. To close the turbine it is necessary to swing the housing back again by hand until the pawl drops into position. A pilot light indicates when a thread is broken at a spinning unit. When the spinning operator notices the pilot light she goes to this spinning unit, opens the turbine, takes the remains of the yarn and the dirt out of the spinning turbine by hand, using a hook, and then closes the turbine again. The disadvantage with this known arrangement is that the operator has to be very alert and also that she can only deal with thread breakages by using a relatively large amount of time and energy.

It is similarly disadvantageous when the spinning turbine has to be opened to be cleaned, without a thread break having been indicated. Periodic cleaning of this nature is essential, on account of the unavoidable deposits of pieces of thread and other kinds of dirt, to permit the production of a good thread and to prevent the occurrence of too many thread breakages. Spinning devices are also known on which cleaning devices are fitted which are introduced into the spinning turbine which is closed by the guiding elements or their housing. In these devices the guiding elements for the fiber material which project into the open side of the spinning turbine remain in their operating position during cleaning and thus the spinning turbine is not accessible from the outside. These devices have the disadvantage that the cleaning apparatus can only be accommodated with difficulty as regards space and'as a rule its front part can only consist of inserted narrow diameter pipes, or of thin channels formed in the guide chamber. Furthermore it is disadvantageous that no means are provided for the rapid opening of the turbine when it is necessary to deal with trouble in the cleaning apparatus or specially dirty conditions in the turbine without losing too much time.

The object of the invention is the provision of a spinning device which obviates the disadvantages of the known arrangements, facilitates operation, produces a good thread and increases production.

According to the invention there is provided a spinning device for spinning threads by the open-end method having a spinning turbine and guiding elements for the fiber material which are movable in relation to the spinning turbine and render its open side accessible from the outside, wherein release means and control members are provided by means of which the relative movements between the spinning turbine and the guiding elements take place automatically. The actuating means which are used here are conveniently thread break detectors which trip the opening of the turbine when a thread breaks, or thread sensing devices which trip the opening of the turbine even when the quality of the thread drops.

Furthermore it is advantageous if the actuating means of a group of spinning devices can be operated together. It is also advisable to provide supplementary control means for opening the turbine manually. Special advantages result in the case of spinning devices in which the open side of the spinning turbine can be made accessible, if each spinning turbine has associated with it a cleaning arrangement which is introcued into the open side of the spinning turbine.

Embodiments of the invention will now be described in greater detail by way of example and with reference to the accompanying schematic drawings, in which:

FIG. 1 shows the side view of a spinning device in which the guide chamber can be moved away from the spinning turbine in the axial direction and this opening movement is tripped by the release of a spring catch when a thread breaks; a swivelling cleaning device is disposed above the spinning turbine and the position of the guide chamber and the cleaning device in the cleaning position is shown by the dash-dot lines;

FIG. 15 is a side view of the spinning device in FIG. 14 with the spinning turbine opened and the cleaning device introduced; and

FIG. 16 is an elevation of a group of spinning devices A,B,C as in FIG. 14 and 15, taken along the line XVI-XVI, with pneumatic control lines for the automatic opening of one or more spinning turbines; the spinning devices A,B are represented with the turbine closed, the spinning device C with the turbine opened.

In FIGS. 1 and 2 the spinning turbine l is mounted by its shaft la in the nip of two pairs of driving discs 2b, 20 which in turn are supported in the bearing block 2a fixed on the carrying rail 2. The driving belt 3 for the spinning turbine 1 is a tangential belt which is tensioned at each spinning device by an expander roll 3a. The expander roll is swingably disposed on the carrier 2al located on the bearing block 2a, on which carrier there is also mounted so as to be displaceable vertically a brake lb which acts on the shaft la of the spinning turbine. The brake 1b is depressed by the lever arm 3a2 of the expander roll carrier 3al when the expander roll is swung upwards in the direction of the arrow A (FIG. 3) in order to take the load off the belt 3. The expander roll 3a can be swung upwards by a solenoid 3b. In the guide chamber 4 are accommodated the guiding elements for the supply of the fiber material 4f 1 and the delivery of the spun thread 4f2. In the example which is illustrated they consist chiefly of supply rolls 4a, comber rolls 4b, supply channels 4c and delivery members for the thread 412 which leaves the guide chamber 4 at 4d and passes on to the delivery rolls 4e. The supply roll 40 is driven by a through worm shaft 4a2, by means of the gearwheel 4a1, the comber roll 4b by the belt 4bl.

The guide chamber 4 is supported so as to be capable of horizontal displacement on the guide bar 2a which is fixed to a flange 2a2 of the bearing block 2a. In the spinning position the guide chamber 4 is pressed by a spring 2d1 against a pawl 4g] of the pawl lever 4g. For opening the spinning turbine 1 the pawl lever 4g is swung upwards by the control member 6, represented in the example in the illustration as a solenoid, so that the pawl 431 disengages from the notch 2e2 in the bar 2d. The guide chamber 4 is then moved by the spring 2dl by the distance L into the position represented by the dash-dotline, as a result of which the space in front of the turbine 1 becomes accessible from the outside. This opening can be operated manually also, in exceptional cases, by moving the lever 4g by the knob 433. As a rule the opening of the spinning turbine is tripped automatically when a thread breaks or the quality of the thread drops beyond a certain standard.

If opening is to be effected automatically on the breaking of a thread a thread feeler is disposed before the delivery roll 4e as a tripping agent 5 which operates the solenoid 6, by control means and control devices (which are not illustrated), whereupon the guide chamber is moved into the position shown by the dash-dot line in the manner which has been described already. If there is a deterioration in the quality of the thread, due to the spinning turbine becoming dirty or through any other trouble, it is possible for this also to bring about an interruption in the spinning process by the opening of the spinning turbine. In this case a thread sensing head is used as the tripping agent 5 which, for example, in the event of considerable fluctuations in thread thickness generates control currents which likewise energize the solenoid 6. Instead of one tripping agent 5 it is also possible to fit several tripping agents, for example a thread feeler and a thread sensing head which come into effect selectively through the appropriate electrical circuits.

Provision can also be made, by appropriate electrical circuits, for the opening of groups of spinning devices or all the spinning devices on the machine by way of central switches without a thread breakage or deterioration in the thread quality having to take place. This type of opening of the spinning turbine for cleaning purposes is conveniently carried out after a definite period of time in which arrangement the switch or switches tripping the shut-down can be operated manually or through an automatically acting instrument, for example a timing clock.

After the spinning turbine has been opened by the above described means its interior can be cleaned conveniently and thoroughly by equipment introduced from the outside. It is also possible at the same time to inspect the interior of the spinning turbine and the orifices of the guide channels in the guide chamber and if necessary to clean the channel orifices as well. In the example illustrated in FIGS. 1 and 2 the cleaning apparatus 7 disposed on the carrier consists of a pivoted lever 7a, 702 with a tool carrier 7b and cleaning tool 70. If the tool, constructed for example, as a brush is only required to be brought by hand into the cleaning position shown by the dash-dot line, the lever part 7a2 can be dispensed with and the lever is brought by the handle 7a1 into the cleaning position, which is reached when the lever 7a makes contact with the adjustable stop 7d disposed on the carrier 2a1. If the cleaning tool has to be introduced into the opened spinning turbine automatically, a control rod linkage 71 acting on the lever part 7a2 is operated by special control means, for example by a solenoid 7f which is operated by the movements of the guide chamber 4. In place of a solenoid of this kind it is also possible to use hydraulic or pneumatic means through a control rod linkage coupled with the movable guide chamber by way of bell-crank levers, eccentrics, or the like. The operation of the solenoid 7f in dependence upon the movements of the guide chamber can be obtained by appropriate circuits in accordance with the desired degree of automation. A preferred form of construction provides for the automatic introduction of the cleaning tool, the cleaning and the withdrawal of the tool in dependence upon the movements of the guide chamber.

In FIG. 3 the guide chamber 34 is mounted on a piston rod 32d, the piston 32d1 on both sides of which can be acted upon in the compressed air cylinder 32, which is fixed on the bearing block 320, in which it is guided. The reversing valve 36 is operated by the control lever 36b by way of a flexible pipeline 36a. A further control valve 36c is provided for operating a pneumatically actuated cleaning device. The control head 36b] on the control lever 36b can be operated manually or electrically. The switching possibilities of an arrangement such as this are generally the same as has been described for FIGS. 1 and 2. The extended position of the guide chamber 34 is represented by a dash-dot line.

In FIGS. 4 to 7 the guide chamber 44 accommodates a cleaning apparatus 47 consisting of a displaceable guide tube 47a, a tool rod 47b and a tool 47c, also of a driving arm 47d1 fixed on the pivot pin 47d and accommodated in the recess 44c in the guide chamber 44, together with a hand lever 47d2 fixed on the pin 47d. When the spinning turbine 41, shown closed in FIG. 7, is rendered accessible from the outside by the moving away of the guide chamber 44 into the position shown by broken lines in FIG. 4 to 6, the guide tube 470 can be brought into the position shown in FIG. 5 by the lever 47d2 by way of the driving arm 47:11. At approximately the same time the tool rod 47b with the tool 47c is pushed fully into the turbine 41 up to the cleaning position by compressed air which is supplied by means of the hose 47al. After cleaning, the guide tube 470 is swung back into the position shown in FIG. 6, the tool 470 still projecting a little from the guide chamber 44. The tool 47c is now accessible to such an extent that the particles of dirt and fiber adhering to it can be removed. This can be performed by hand with a simple, hook-shaped scraper, or with a motor-driven hand tool with a rotating needle (the socalled fly catcher), which cleans a little more efficiently but is difficult to manipulate.

In the example illustrated the removal of dirt and fly is effected by means of a removal head 48b which is connected by way of a vacuum line 48 to a reservoir 48a and is associated with each of the spinning devices and can be moved by hand or mechanically and automatically from its rest position into the position shown by the dash-dot line on the tool 47b, (FIG. 4). After quite a short time the removal of the dirt is completed and the removal head 48b is lifted up again. At the same time the supply of compressed air is disconnected from the guiding tube 47a and as shown in FIG. 7, so the tool 47b is again withdrawn fully into the guide chamber 44 under the action of a restoring spring, (not shown). During and/or after this withdrawal the turbine 41 is closed again by bringing up the guide chamber 44. Instead of using the hand lever 47d2 the arm 47d1 can also be swung automatically by special control means, for example by a solenoid 46 which is represented by the dash-dot line in FIG. 5.

In FIGS. 8 and 9 the spinning turbine 81 is mounted in a closed bearing housing 82a and is driven by a belt 83 by way of a driving pulley 81b. A cleaning device 87 is accommodated in the guide chamber 84 which consists of a guide rod 87a and a tool 870 and also of a supply line 87d for cleaning fluid which leads to a spray nozzle 87dl. On and after the opening of the spinning turbine the cleaning tool 87c is brought into the cleaning position shown in FIG. 8 by the shifting of the guide rod 87a from the rest position shown in FIG. 9. This shifting can be done by hand or by mechanical means, for example by a rack gearing 84a2 which is operated by a rotating shaft in the guide chamber in a manner which is not illustrated in greater detail. This drive is controlled by way of clutches, or the like, in such a way that the movement of the guide rod 87a is conveniently adapted to the series of movements of the spinning device. The supply of the cleaning fluid is regulated by a controlled valve 87:12. The jet of cleaning fluid indicated by the line 87d3 can be injected or sprayed directly into the opened turbine 81, it is also possible for the jet of fluid 87d4 to be sprinkled or sprayed on to the cleaning tool prior to its introduction into the open turbine.

Also disposed on the guide chamber 84 is a removal tool 88 which swings round a pin 88a and which cleans the dirt and fiber particles from the cleaning tool 870 when it has been withdrawn from the spinning turbine. The removal tool 88 can be constructed as illustrated, in the form of a removal roller, the outer surface of which is matched to the shape of the cleaning tool and is provided with a removal fitting, of small hooks or the like. If, beside the axle of the removal roller, there is disposed a driving wheel 88d which is driven, in a manner not shown in detail, by rotating parts of the guide chamber, it is possible, by swinging the lever 88b slightly in the direction of the arrow B, to obtain friction contact between the axle of the removal wheel 88 and the driving wheel 88d with the result that the removal wheel 88 rotates. Simultaneously it is thereby also possible to cause the tool 87c to rotate if it is rotatably disposed on the guide rod 87a.

Instead of a cleaning roller 88 it is also possible to use a pneumatically operating removal tool 108, see FIG. 10. The removal tool may be a suction or a blast head. It is situated on the resilient tubular part 108a which is connected to the rigid guide tube The bearing part 104a disposed on the guide chamber 104 is used as a bearing support in the case of a movable removal device and as a support for the guide tube 108b in the case of a fixed removal device.

FIGS. 11, 12 and 13 illustrate various cleaning tools. In FIG. 11 the cleaning tool 1172 is a brush which is fixed on to a thin and resiliently flexible carrier 117b. The brush certainly has a good coarse cleaning action but it only picks up adhering dust particles if cleaning is carried on for a very long time. The cleaning head 1272 illustrated in FIG. 12 consists of a scraping tool 12701 and a brushing tool 127c2. Both tools are fitted on resilient tool arms 127b which are so shaped that the distance of the two tools from one another in the released, withdrawn state corresponds roughly to the turbine opening; this position being indicated by the dash-dot line. After being inserted, the tools strike the bottom of the turbine and the anus flex outwardly until the tools have reached the cleaning position shown.

In FIG. 13 a bowl 137c1 is disposed on the carrier tube 137 through which compressed air or a cleaning fluid is ejected. A second brushing tool 137c2 is fixed on the tube 137 by a resilient carrier 137b. Outside the spinning turbine the carrier 1371: takes the relaxed shape shown by the dash-dot line. In all three forms of construction shown in FIGS. 11, 12 and 13 it may be convenient to suck, or blow the particles of dirt and fiber through the bore lllal of the turbine shaft or through a tube l11a2 inserted therein (FIG. 13), provided this bore is not being used for leading off the thread. The tool 13721 in FIG. 13, which also has a scraping action, reinforces the sucking off of the dirt particles through the bore lllal or 1 1 1a2.

In FIGS. 14, 15 and 16 the spinning turbine 141 is mounted in a bearing block 1420 and driven by means of the belt 143 on the free part of its drive shaft 141a between the bearings. The bearing block 142a is guided so as to be vertically displaceable in the guide plate 14212 fixed on the supporting bench 142. In the example shown in the drawing the displacement is effected pneumatically by means of the piston rod 142d which is connected with the bearing block 142a and is guided in the compressed air cylinder 142b1 disposed on the guide plate 142b, the guide chamber 144 being fixed immovably to the machine frame. Associated with each spinning device is a pneumatically moved cleaning device 147, the compressed air cylinder 147a of which is pivotally mounted in the bearing 14701 on the supporting bench 142 and is supported by its face147a2 on the lifting rod linkage 14723 and 14724, which is represented diagrammatically in a simplified form. Rotatably mounted on the guide plate 142b is an axle 14221 on which rests a lever 142 e2 which is operated by way of the stop ring 14223 by the piston rod 142d. Fixed on the other side of the axle 14221 is a lever 142e4 against which the rod 14724 is braced.

The cleaning tool 147c is disposed on a bent-over extension of the piston rod 1471). Fixed to the cylinder 147a is a gliding runner 147a3 which co-operates with the brake rod 149. When a thread breaks the spinning turbine 141 is opened by the thread feeler 145 (FIG. 15) operating the control valve 146 for the compressed air cylinder 142121, through a control pipeline 145a shown in FIG. 16, as a result of which the spinning turbine is lowered into the position represented in FIG. 15. The valve 146 can also be actuated by the hand lever 146a shown by the dash-dot line in FIG. 15. During the lowering, the cylinder 1470 of the cleaning apparatus 147 is swung by the control rod linkage 14723, represented diagrammatically, so that the piston rod 147b controlled by the valve 146a pushes the cleaning tool 147c into the cleaning position, (FIG. 15). In this process a certain time lag is effected for this inserting in relation to the lowering of the spinning turbine by means of the appropriately constructed valve 146, the delay period of which is adjustable. Towards the end of the swinging movement of the cylinder 147a, the runner l47a3 presses against the brake rod 149 so that the brake shoe 149a fixed thereto lightly brakes the turbine.

To obtain a more powerful cleaning action it is possible to provide a sprinkler nozzle 147f disposed in the guide chamber 144, to sprinkle or spray a cleaning fluid into the turbine 141, or on to the tool 1472 (FIG. 15). The supply line to this sprinkler nozzle is connected to a common line 147f1 for a group of spinning devices. The dirt can be removed from the withdrawn tool 1470 by a hand tool, mechanically or by suction or blowing. It is also possible, however, as shown in FIG. 14, to carry out this removal automatically by a suction noule 148a associated with each spinning device and connected to a common suction tube 148. Further suction nozzles, not shown in the drawing, can be disposed on this suction tube for the purpose of cleaning other parts of the spinning device.

The diagrammatic switch system for fully automatic opening, cleaning and thread joining in FIG. 16 shows the principal circuitry. Associated with each spinning device is a switch box 145k. The compressed air pipelines are shown by dash-dot lines. By way of the electric lead 145a, to which current is conducted from the lead 145h, the thread feeler 145 trips the operation of the valve 146, whereupon the turbine descends. At the same time, through the electric lead 145b which is controlled by the valve 146, the valve 146a is operated as a result of which the cleaning apparatus is moved into the turbine. As soon as the turbine descends the expander roll 143a (see FIG. 15) is raised a little from the belt 143 (FIG. 14) by means which are not illustrated, so that the turbine is partially or completely stopped. In addition the turbine is braked by the brake shoe 149a. The rotating parts accommodated in the guide chamber 144 are also stopped, by means which are not illustrated. After a definite period of time, as required for the cleaning, the valve 146 is reversed automatically so that the turbine is moved upwards and the cleaning apparatus is returned to its rest position. As the turbine is closed, the parts which had been stopped in the guide chamber and the turbine are started up again. A returning device, which is not illustrated, automatically inserts the end of the thread in the guide chamber, or the spinning chamber, as a result of which the thread is joined on again. The suction mechanism 148, 148a cleans the withdrawn cleaning tool 1472.

To make it possible to open a group of spinning devices at the same time, individual leads 145f run from the central control lead 1456 which is operated by a central switch 145d, for example by way of a timing clock 1452; the lead 145g acts as the current return line. When the switch 145d is operated the current pulses needed for the opening of the turbine pass along these leads to the valves 146.
